There is a compartment for installing an optional internal Fax/Modem.
When installed, the fax/modem has a port that is located at the left side
of the computer.

A Fax/Modem is a composite device that performs both functions implied
in the name.

A fax (facsimile) machine transmits data in essentially the same way as a
modem, but with the addition of a scanning device for input and a thermal
printer for output.  Thus one can send away information on paper through
the machine's scanner.

The fax part of a Fax/Modem is somewhat different.  In a Fax/Modem the
scanning and printing functions are removed leaving the transmission
hardware.  The data transmitted is then generally taken in the form of
files from the computer which are transmitted using software specially
designed for the Fax/Modem.
